如何更改或删除a的行为spyOn
?当我尝试覆盖它时,出现以下错误:Error: getUpdate has already been spied upon
var data1 = 'foo';
var data2 = 'bar';
describe("a spec with a spy", function(){
beforeEach(module('app'));
var $q;
beforeEach(inject(function(_updateService_, _$q_){
updateService = _updateService_;
//spy the results of the getUpdate()
$q = _$q_;
var deferred = $q.defer();
deferred.resolve( data1 );
spyOn(updateService, 'getUpdate').and.returnValue(deferred.promise);
}));
describe('and here the spy should be different', function() {
it('returns a different value', function() {
var deferred = $q.defer();
deferred.resolve( data2 );
spyOn(updateService, 'getUpdate'); //ERROR HERE
updateService.getUpdate.and.returnValue(deferred.promise);
...
});
});
...
当我删除第二个spyOn时,测试不起作用。
我该怎么做呢?
